What are the general types of bidding for engineering construction?
Strictly speaking, bidding is divided into open bidding and invitation bidding.
Open bidding means that the tenderer invites unspecified legal persons or other organizations to bid by means of tender announcement, which is also called unlimited competitive bidding. Adopting this bidding method can provide equal competition opportunities for all qualified contractors, and the employer has more choice space, which is conducive to reducing the project cost, improving the project quality and shortening the construction period.
Invited bidding means that the tenderer invites a specific legal person or other organization to bid in the form of an invitation to bid, also known as limited bidding. Adopting this bidding method, because the number of bidders invited to participate in the competition is certain and generally few, it can not only save the bidding cost, but also improve the probability of winning the bid for each bidder, so it is beneficial to both bidding and tendering.

How long does it take to complete a project bidding procedure?
Bidding procedures are divided into general procedures, simple procedures and special procedures according to the nature of the project.
The general procedure refers to the bidding procedure of directly determining the winning bidder after bid opening (applicable to the lowest price method) or determining the winning bidder through bid evaluation without pre-qualification. In this program, the bidding period generally takes 15 ~ 25 days.
Summary procedure refers to the bidding procedure of determining the winning bidder by drawing lots without pre-qualification. The summary procedure is applicable to the bidding of projects other than simple projects that can be selected by lottery. In this program, the bidding period generally takes 5 ~ 10 days.
Special procedures refer to the bidding procedures for pre-qualification and determination of the winning bidder through bid evaluation. Special procedures are applicable to the project bidding that can be prequalified after approval. The bidding period of such procedures is generally 25 ~ 35 days.
